Product details

Overview

JAN1N4115D-1 from Microsemi is a 500 mW, 22 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.

For engineers reviewing the JAN1N4115D-1 datasheet, JAN1N4115D-1 pinout, JAN1N4115D-1 application, or JAN1N4115D-1 equivalent, key selection factors include its 1% Zener voltage tolerance, 150 Ω dynamic impedance at 250 mA, 0.01 µA reverse leakage at 17.6 V, radiation-hardened construction, and hermetic DO-35 axial-leaded package suitable for military-grade thermal and ESD environments.

Technical Context

This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 22 V at 250 mA test current, exhibiting +0.090 %/°C temperature coefficient and 1 µV/√Hz noise density - optimized for low-noise reference circuits where stability across -65 °C to +175 °C is required.

Its metallurgical bond structure ensures robust junction integrity under thermal cycling and radiation exposure, while the DO-35 glass package provides hermetic sealing and non-ESD-sensitive operation per MIL-STD-750 Method 1020, supporting use in mission-critical analog biasing and voltage clamping functions.

Dynamic Impedance (Z_ZT)	150 Ω at 250 mA - ensures low output impedance for effective ripple suppression in regulated DC supplies.
Reverse Leakage (I_R)	0.01 µA at 17.6 V - minimizes standby current loss in low-power sensor bias networks.
Noise Density (N_D)	1 µV/√Hz - critical for ultra-low-noise analog references in precision instrumentation front-ends.
Temp Coefficient (αV_Z)	+0.090 %/°C - allows predictable drift compensation in wide-temperature-range voltage references.
Junction Temp Range	-65 °C to +175 °C - validated for operation in space-grade and jet-engine-mounted electronics.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4115US-1	Same 22 V/1% spec but in DO-213AA surface-mount package; no axial leads.	Used where PCB real estate is constrained and reflow assembly is required instead of through-hole mounting.	Select when automated SMT production is mandatory and thermal resistance to ambient is acceptable at 300 °C/W.
JANTXV1N4115D-1	Identical electrical specs but qualified to JANTXV level (enhanced screening vs. JAN); same DO-35 package.	Deployed in higher-tier defense subsystems requiring extended burn-in and lot acceptance testing beyond JAN requirements.	Choose when program-level reliability mandates JANTXV screening for mission-critical flight computers.

Compared with JAN1N4115D-1, 1N4115US-1 trades axial-leaded mechanical robustness for SMT compatibility, while JANTXV1N4115D-1 adds screening rigor without altering electrical behavior - enabling direct substitution only when qualification level matches program requirements.

FAQ

What is the Zener voltage tolerance of JAN1N4115D-1?

JAN1N4115D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This means its nominal 22 V Zener voltage is guaranteed between 21.78 V and 22.22 V at 250 mA test current and 25 °C, supporting high-accuracy reference design without post-manufacturing calibration.

Is JAN1N4115D-1 suitable for space applications?

Yes, JAN1N4115D-1 is qualified to JANS level per MIL-PRF-19500/435 and exhibits inherent radiation hardness per Microsemi MicroNote 050. Its metallurgically bonded junction and hermetic DO-35 package make JAN1N4115D-1 appropriate for low-earth orbit satellite power conditioning and onboard analog reference circuits.

What is the maximum reverse leakage current for JAN1N4115D-1?

The maximum reverse leakage current (I_R) for JAN1N4115D-1 is 0.01 µA at 17.6 V (80% of V_Z). This ultra-low leakage ensures minimal current draw in high-impedance bias networks and preserves accuracy in precision sensor excitation circuits using JAN1N4115D-1.

Does JAN1N4115D-1 require external heat sinking?

No, JAN1N4115D-1 does not require external heat sinking under typical conditions. With a thermal resistance of 250 °C/W junction-to-lead (at 10 mm lead length), it safely dissipates up to 500 mW at 25 °C ambient. Derating begins linearly at 50 °C lead temperature, reaching zero dissipation at 175 °C - consistent with JAN1N4115D-1's rated junction range.

How is polarity marked on JAN1N4115D-1?

JAN1N4115D-1 uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode for Zener regulation. This marking complies with JEDEC DO-35 standards and is visible on the glass body; correct orientation is essential to avoid forward conduction instead of breakdown regulation in circuits using JAN1N4115D-1.
